ILQii'i. it may concern: it known that L 'fi' rmamr B. SMITH, a citizen of the United States, and a resident oi: Li!\YEOECQVlllQ, in the count-y of Lawrence e of lllinois, have invented a new and us: ul Tank-Car Heater of which the following a specification.

My invention is tank car heater and has as its all important object the provision of a heater of this character for heating the liquid contents of the car such as heavy oils tempere'ure where the same may be ili, disp or drawn from the car. Ir anther the invention embodies a tank car heater which wili he securely anchored in the tank and is so constructed to prevent leakage oi the steam or other heating agent winch usually results in the damaging ot the contents of the tank.

it is a turther ohjectof the invention to provide a heater of this character which may be readily taken from the tank tor repairs and then replaced and which will also permit the tank to be repaired and cleaned.

Still another oldest of my invention embodies a tank car heater heated through the medium of steam and which is so constructed as to obviate bursting oi the hcatcrpipcs due to freezing of condensed steamthercin.

li'ilh the preceding and other objects and advantages in niinch the invention consists in the novel combination o'i elements. constructions and arrangements ol parts and operations to be hereinafter enlarged upon, claimed and illustrated in the accompanying drawings, wherein: I

Figure l is a view partly in longitudinal section and partly in elevation of a tank car equipped with my heater;

1 i -uz'e is a vertical sectional view of the same;

Figure a top plan view, parts of the tank being shown in broken lines and parts of the healer being hrolrcn away; and

Figure, 4 is a fragmentary transverse sectional view t; ircn on iine llal of Figure 3.

licierring in detail to the drawings wherecharzu-tei reference designate iarts throughout the several designates a modern nv improved heater is aphides plurality of lon leirs 5 placed upon the a and disposed transversely thereof. Each of these headers is provided with laterally disposed ears or feet 7 at their ends which are removahly fastened to the walls of the tank by fastenings 8.

Parallel tubes 9 extend from one of the intermediate headers to the other while tubes 10 extend from these intermediate headers to the end headers. The headers (i are provided with plugged openings 11, the plugs of which may be removed to permit additional pipes to be employed if desired.

The intermediate headers are formed with nipples 12 at their crest, one of which communicates with a steam pipe 13 extending vertically through the bottom of the tank while the other communicates with an outlet pipe H also extending vertically through the bottom of the tank.

The bottom of the tank is provided with the usual control *alve in its bottom and is designated in its entirety at 15. It will be obvious that steam or other heating fluid passing through the pipe 13 will circulate through the headers and tubes and pass out by way of the pipe 14. and as these tubes are submerged in the fluid contained in the tank car. this fluid will be retained at such temperature as to permit the same to be readily drawn from the tank.

It is to be understood that the form oi? my invention herein shown and described is to be taken as a preferred example of the same. and that various changes in the shape, size and arrangement of parts may he resorted to without departing from the spirit of the invention or the scope of the suhjoined claim.

llaving thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, is:- I

The combination with a tank car, of a plurality of longitudinally bowed headers arranged transversely of the bottom of the tank, fleet carried by the ends of the headers and dctach ably secured to the tank, longitudinally arranged heating tubes communicating with the headers for heating the liquid contained in the tank, a steam pipe passing vertically through the bottom of the tank and having communication with one of the headers, and an outlet pipe communicating with one of the remaining header l VILLIAM B.
